No, AC HVAC is not a furnace. AC HVAC stands for air conditioning heating, ventilation, and air conditioning, and is a system that is used to regulate the temperature, humidity, and air quality of a space. It is composed of several components, including an outdoor condenser unit, an indoor evaporator coil, and a blower fan. The condenser unit is responsible for cooling the air, while the evaporator coil is responsible for heating the air. The blower fan circulates the air throughout the space. A furnace, on the other hand, is a device that is used to heat air and distribute it throughout a space. It is composed of a heat exchanger, a blower fan, and a thermostat.
